NASA-UAP-D005, Apollo 17 Crew Debriefing for Science, 1973
Apollo 17 was the ninth crewed U.S. mission to the Moon, and the sixth to land Astronauts on the lunar surface. This document is an excerpt from the Apollo 17 Crew Debriefing for Science on January 8, 1973, in which Dick Henry, co-investigator on the ultraviolet experiment on Apollo 17, discusses seeing results that were unexpected. • Pages 119-120. “One of the most exciting results of X-ray astronomy was the fact that an X-ray background was observed over the sky that nobody had expected, and part of this is the gamma-ray background that Dr. Trombka talked about. In the UV, nobody knows, but you never know until you look. You do have to deal with this background of stars that we know is there. So, we did look at a large number of different points at high galactic latitudes, both north and south. The spectrum that we see is above this dark count. In other words, this abnormally high dark current did not, in fact, interfere with that experiment. The spectrum that we see looks like the spectrum of the hot star; however, we know that there were no hot stars within our field of view. Therefore, the most conservative interpretation, I think, is that what we're seeing is light from hot stars in the galactic plane going up out of the plane and reflecting off interstellar dust. There are certain characteristics of the spectrum, though, that don't fit that theory, and it's at least possible that this is extragalactic radiation. I'm looking forward very much to the detailed computer study of this, but it's going to take a long time.”

Where this file fits in the PURSUE archive
This file is one of NASA's 33 files in the Trump PURSUE disclosure. Within the NASA agency block it ranks #15 of 33 by Anomalousness Index. Across the entire 294-file archive it ranks #118 of 294.
That places it in the lower-scoring band of the archive (118 of 294 by score), typical of investigative-record style files where the report is paper-based rather than instrumented.
For the broader cluster context, this file is part of Apollo 17 UFO Records - the 4-file Apollo 17 PURSUE cluster, including the triangular-formation lunar image and Schmitt light-flash debriefing. The cluster page walks through all 4 member files with regional grouping, sensor breakdown, and standout analysis.
Anomalousness Index: 59/100
Evidentiary weight that this encounter remains unexplained after conventional analysis. Not a probability of extraterrestrial origin - that number is not honestly computable from the released files and this tracker refuses to publish it.
🤖 AI-ASSISTED SCORING · methodology
The six rubric components break down for this file as follows. Each component has a weighted contribution to the final score; the per-component explanation below describes what this file's particular value on that component means in the rubric's framework.
Reported by a witness with no instrumented record. The lowest tier in the rubric's sensor axis. Eyewitness perception in field conditions, even when the witness is highly credentialed, scores below capture by any instrumented modality.
Astronaut witness on the official federal record. The highest tier in the rubric and essentially unique in the PURSUE archive - only the Borman/Lovell Gemini 7 file fits this tier, which is the structural reason it is the sole 72 in the archive.
Single-witness or single-instrument capture. Every file in the PURSUE archive scores at this corroboration tier on the released metadata - the rubric records the honest limit of the underlying record rather than inferring multi-witness corroboration that the released summaries do not establish.
No kinematic measurements - speed, acceleration, vector - are published in the released file with sufficient precision to score on the kinematic axis. The rubric does not infer kinematic anomaly from narrative observer estimates. Every file in the archive carries this value, which is itself an observation about the disclosure: kinematic-grade telemetry was not part of what was released.
A conventional candidate explanation has been considered but is not dispositive. Every file in the archive scores this way - reflecting that the underlying release metadata systematically caveats strong determinations in either direction. The released summaries warn against reading them as conclusive analytical judgments, and the rubric respects that.
Released as open after formal review by the originating agency. The file passed through a review process and was published in that posture - a stronger disposition signal than 'unresolved with no review,' because review has occurred and the open status is the agency's published conclusion.
Bottom line on the score: the Anomalousness Index of 59/100 reflects evidentiary weight that this specific file's encounter remains structurally unexplained by the rubric's six axes - it is not a claim that the underlying event involved anything non-conventional, and it is not comparable across rubrics that use different weights.
